They all say "texture" well. Or Textures.
Given the topic, the first and last are my favorites. The comp feels better balanced in the last. The first adds that additional window for more textures, but is probably not necessary. I am pretty sure I would have taken that shot, had I seen it, but I think the last is better.
Matter of taste, but they all feel a bit overprocessed to me, esp the middle two which have a bit of HDRish look without strong blacks. The middle ones feel a bit overly busy.
So, I'd go with the last. Wish I had an entry but I am not happy with what I could do.
